1 Claim. l

This invention relates to sprinkler heads for spray nozzles of the typeused on lawn sprinklers and the like, and in particular includes a bodyhaving a base threaded to receive a water supply pipe or stand with aclosed outer end having spaced openings therethrough and with a baillecap threaded on the outer end and provided with an outlet or dischargeopening offset from the opening in the end of the body and having asemi-circular baille angularly disposed in relation to the opening.

The purpose of this invention is to provide an improved sprinkler headhaving a baille nut adjustably mounted on the outer end and a lock nutfor securing the baffle nut in adjusted position.

Various types of sprinkler heads have been provided and openings havebeen used in various positions in the ends of nozzles but it isdiillcult to provide adjusting means for regulating the spray withoutchanging the size of the opening and without danger of forming sedimentaccumulating pockets in the head. With this thought in mind thisinvention contemplates a sprinkler head having a body with dischargeopenings in the outer end and with a baille nut secured in adjustedpositions on the body by a' lock nut and provided with baille surfacespositioned in the path of water passing through the head.

The object of this invention is therefore, to provide means for formingthe outer end oi a sprinkler head whereby the passage oi water throughthe head is obstructed by offset passages and protruding bailles.

Another object of the invention is to provide an improved spray nozzleor sprinkler head that may be threaded on the ends of pipes or sprinklerstands now in use.

A further object oi the invention is to provide an improved sprinklerhead having a baille adjustably positioned in relation to the body whichis of a simple and economical construction.

With these and other objects and advantages in view the inventionembodies a body having an internally threaded base with an externallythreaded head with spaced openings extended through the outer end of thehead positioned adjacent the side walls thereof, a baille cap threadedon the head of the body and a lock nut also threaded on the said head.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawings whereinFigure 1 is an elevational view illustrating a semi-circular bailleadjustably mounted on the outer end of the body of a sprinkler head.

Figure 2 is a longitudinal section through the sprinkler head and captaken on line 2-2 of Figure 1.

Figure 3 is a plan view of the body of the sprinkler head shown inFigures 1 and 2 with the baille cap removed.

Figure 4 is a view similar to that shown in Figure 1 illustrating amodification wherein the baille cap is replaced by a baille cap havingan opening in the center thereof. v

Figure 5 is a vertical longitudinal section through the head shown inFigure 4 being taken on line 5-5 of Figure 4.

Figure 6 is a plan view of the head and body shown in Figures 4 and 5with the baille cap removed.

Figure 7 is a detail taken on line 1--1 of Figures 5 and 6 illustratingthe sloping openings lin the outer end ofthe body head'.

Referring now to the drawings wherein like reference characters denotecorresponding parts the improved sprinkler head of this inventionincludes a body I Il, a baille nut I I and a lock nut I2.

The body I0 is provided with a hexagonal base I3 having pipe threads I4on the inner surface for receiving a Water supply pipe or tube of astand and at the upper end of the body is a head I5 having a centrallydisposed boss I6 with openings I'l and I8 extended through the outerwall I9 and the outer surface oi the head is provided with threads 2D.The inner surface of the head I5 is provided with a bore 2l having aconical surface 22 that extends into the bore I6.

The baille nut I I is provided with a hexagonal wall 23, internallythreaded to receive the threads 20 of the head I5 of the body I0 and theouter end of the nut is closed by a web 24 having a centrally disposedopening 25 therethrough and a semi-circular baille 26 with a slopingunder surface 21 is carried by the web 24 on the outer end of the baillenut through a base 28. The baffle nut lI may be turned to adjust theposition thereof in relation to the end of the body Il) and when thebaille nut is in the desired position it is secured in this position bylock nut I2, which is also threaded on the threads 20.

In the design shown in Figures 4-7 inclusive the sprinkler head isformed with a body 30 having a hexagonal base 3I with threads 32 on theinner surface and a head 33 on the outer end is provided with acentrally disposed bore 34, and inclined openings 35 are provided in aweb 36 forming the outer end of the head 33. The outer surface ci thehead 33 is provided with threads 31 and a baille cap 3B with a centrallydisposed opening 39 in a web 4|] on the outer 3 end is threaded on thethreads 31 on the outer surface of the head of the body 30. The positionof the baffle cap or nut 38 may be adjusted by turning the nut on thethreads 31 and the nut is secured in adjusted position by a lock nut 4|.

With the parts arranged as shown in Figures 1 and 2 the water passingthrough the openings l1 and I8 enters a chamber 42 inside of the balenut or cap Il and from this chamber the water passes through the opening25, striking the under surface 21 of the semi-circular bale 26 therebyproviding a fan shaped outwardly extended spray. The amount of watersprayed and the size of the spray is controlled by the position of thebafie cap Il on the head I and the baille cap or nut is adjusted andsecured in the adjusted position by the lock nut I2.

In the design shown in Figures 4 and 5 water passing through the slopingopenings 35 enters a chamber 43 inside of the baiile cap or nutv with a.swirling action and the circulating water passing around the innersurface of the cap passes to the opening 39 and isv sprayed outwardly.The amount of water and also the size of this spray is adjusted by theposition of the cap 38 on the head of the body 38 and this cap issecured in adjusted position by a lock nut 4|.

The sprinkler head of either design may be made in different sizes toaccommodate different types and sizes and the baiiie nut may be securedon the outer end of the head by any suitable means.

It will be understoodv that other modifications may be made in thedesign and arrangement of the parts without departing from the spirit ofthe invention.

What is claimed is:

In a sprinkler head, the combination which comprises a cylindrical bodyhaving a web extended across the upper end and said web having acylindrical centrally positioned boss extended from the4 outer surface,said web also having oppositely positioned openings extendedtherethrough and said openings positioned between the periphery of theboss and the periphery of the body, said body having a hexagonal baseand the inner surface of the lower part of the body and the outersurface of the upper part of the body being provided with threads, a nuthaving a hexagonal body with a cylindrical cavity therein and the innersurface of said body being threaded to receive the threads of the upperpart of said cylindrical body, and a nut having a centrally disposedfrustro-conical shaped section extended from the outer end and acentrally positioned opening extended through said outer end, said nutbeing threaded on the upper end of said cylindrical body and saidfrustro-conical shaped section of the nut having a cavity in one sideproviding an overhanging outer end thereby forming a -spray baiilespaced from the outer end of the nut and positioned to extend over saidcentrally disposed opening through the nut,r and a lock nut threaded onthe upper end of the body and positioned to coact with the nut fromwhich the frustro-concal shaped section extends thereby providing meansfor adjusting the position of the said nut in relation to the end of thecylindrical body.
